System and method for peer-to-peer management through policy and context replication

ABSTRACT

A method of context replication including receiving a first context item at a first system in a network, determining that the first system is a context management master system, establishing a first peer-to-peer session with a second system in the network in response to determining that the first system is the context management master system, and providing, from the first system, the first context item to the second system.

FIELD OF THE DISCLOSURE

This disclosure relates generally to information handling systems, and relates more particularly to peer-to-peer management through policy and context replication.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements can vary between different applications, information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, data storage systems, and networking systems. An information handling system can include virtual machines that run operating systems and applications on a common host system.

FIG. 1 illustrates a network 100 for one or more information handling systems. For purpose of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, an information handling system may be a personal computer, a PDA, a consumer electronic device, a network server or storage device, a switch router or other network communication device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include memory, one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, and operates to execute code. Additional components of the information handling system may include one or more storage devices that can store code, one or more communications ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.

Network 100 includes systems 110, 120, and 130 that are connected together via one or more communication interfaces. Network 100 represents a home network or small business network. For example, where network 100 represents a home network, system 110 can represent one or more desktop computers, system 120 can represent one or more laptop computers, and system 130 can represent one or more mobile devices such as smart phones, tablet devices, or other mobile computing devices. In another example, where network 100 represents a small business network, system 110 can represent one or more workstation or desktop computers, system 120 can represent one or more laptop computers, and system 130 can represent one or more mobile devices such as smart phones, tablet devices, or other mobile computing devices. In a particular embodiment, network 100 includes other systems or devices, such as a game console, a television, a set-top box, another media device, a memory storage array, a network switch, a router, a firewall, or other network device. Systems 110, 120, and 130 are connected together via one or more local area network (LAN) or wireless network (WiFi) interfaces, such as an Ethernet interface, a universal serial bus (USB) interface, or another LAN interface, an IEEE 802.11 a/b/g/n interfaces, a Bluetooth interface, or another WiFi interface, or a combination thereof, as needed or desired. In a particular embodiment, network 100 is also connected to a wide area network (WAN) such as a digital subscriber line (DSL) network, an Internet service provider (ISP) network, or another WAN, as needed or desired.

Network 100 is characterized in that systems 110, 120, and 130 are not maintained and managed by a centralized system. Thus, systems 110, 120, and 130 can be provided with policies, software, drivers, security keys, and the like, by a user of network 100. In a particular embodiment, each of systems 110, 120, and 130 are maintained and managed separately. As such, a user of network 100 can determine a network access policy to be implemented in the network, and can separately set up each of systems 110, 120, and 130 with the network access policy. For example, each of systems 110, 120, and 130 can be separately set up to enforce a parental control policy, a power management policy, or the like. The user can likewise determine that each of systems 110, 120, and 130 are to be provided with common software or device drivers, and can separately install the software or device drivers on each system. Further, the user can separately provide each of systems 110, 120, and 130 with a common security key, such as a WiFi access credential for network 100, a network password, or the like.

In another embodiment, maintenance or management of one of systems 110, 120, or 130 is propagated through network 100, such that the other systems are similarly maintained and managed. As such, the user of network 100 can determine a network access policy to be implemented in the network, and can set up one of systems 110, 120, or 130 with the network access policy, and can direct that system to propagate the access policy to the other systems. For example, system 110 can be set up to enforce a parental control policy, a power management policy, or the like, and system 110 can propagate the policy to systems 120 and 130. The user can likewise determine that each of systems 110, 120, and 130 are to be provided with common software or device drivers. The user can install the software or device drivers on one of systems 110, 120, or 130, and the installation can be propagated to the other systems. Further, the user can provide one of systems 110, 120, or 130 with a security key, such as a WiFi access credential for network 100, a network password, or the like, and the security key can be propagated to the other systems.

FIG. 2 illustrates an embodiment of network 100 where system 110 receives a network access policy 210 and a hardware access policy 220. For example, network access policy 210 can include a WiFi access credential, a parental control policy, or another policy that governs the access to a network resource. Hardware access policy 220 can include a USB access policy that governs the ability of system 110 to transfer files to, or read files from a USB storage device, or that permits only registered USB storage devices to be used on the system. Network access policy 210 and hardware access policy 220 can be implemented on system 110 by a user of network 100, or can be received from another system, such as a policy management system (not illustrated).

In this embodiment, system 110 operates as a master system for policy management to distribute network access policy 210 and hardware access policy 220 to systems 120 and 130. Here, when system 110 receives network access policy 210, a first copy 212 of the network access policy is provided to system 120, and a second copy 214 is provided to system 130. Similarly, when system 110 receives hardware access policy 220, a first copy 222 of the hardware access policy is provided to system 120, and a second copy 224 is provided to system 130. In a particular embodiment, system 110 is designated as the policy management master system based upon a configuration of network 100 where the designation is static and is limited to the system. In another embodiment, system 110 is designated as the policy management master system based upon the fact that network access policy 210 and hardware access policy 220 are first provided to the system. Here, for example, if network access policy 210 had been received by system 120, then system 120 would operate as the policy management master system to provide copies of the network access policy to systems 110 and 130. In yet another embodiment, system 110 is designated as the policy management master system based upon the fact that the system is logged as the policy management master system for network 100. Here, any one of systems 110, 120, and 130 can be logged as the policy management master system for network 100, for example by a user who has a password authentication to make policy changes to the network.

FIG. 3 illustrates an embodiment of network 100 where system 120 receives software 310. For example, software 310 can include a new software program, an update to an existing software program, a device driver, or the like. Software 310 can be provided to system 120 by a user of network 100, or can be received from another system, such as a software or driver update system (not illustrated). In this embodiment, system 120 operates as a master system for software management to distribute software 310 to systems 110 and 130. Here, when system 120 receives software 310, a first copy 312 of the software is provided to system 110, and a second copy 314 is provided to system 130. System 120 is designated as the software management master by one or more of the methods described above.

FIG. 4 illustrates an embodiment of network 100 where system 130 receives a security key 410. For example, security key 410 can include a WiFi or other network access password, an encryption key, or another type of security information, as needed or desired. Security key 410 can be provided to system 130 by a user of network 100, or can be received from another system, such as a security update system (not illustrated). In this embodiment, system 130 operates as a master system for security management to distribute security key 410 to systems 110 and 120. Here, when system 130 receives security key 410, a first copy 412 of the security key is provided to system 110, and a second copy 414 is provided to system 120. System 130 is designated as the security management master by one or more of the methods described above. The skilled artisan will understand that the roles of policy management master system, software management master system, and security management master system are roles that can be assumed by any one or more of systems 110, 120, and 130.

FIG. 5 illustrates a system 500 similar to systems 110, 120, or 130. System 500 includes a peer-to-peer agent 510, a context management framework 520, and a group of context items 530. Context items 530 include policies 532, software 534, drivers 536, and security elements 538. When system 500 receives a new or updated context item 530, context management framework 520 invokes peer-to-peer agent 510 to establish a peer-to-peer session with another system. Context management framework 520 operates to determine if the other system has received the context item 530. If not, context management framework 520 becomes the master system for the context item 530 can directs peer-to-peer agent 510 to provide a copy of the context item to the other system. In the other system, a context management framework similar to context management framework 520 operates to install the copy of the context item in the other system. In this way, system 500 operates to propagate changes in the context of the system to other systems in the network. In a particular embodiment, context management framework 520 can negotiate with the context management framework of the other system to establish which system is the master system. Here, system 500 can provide the copy of the context item 530, and also cede the control of context management to the other system, and the other system can operate to propagate changes in the context of the system to other systems in the network.

In a particular embodiment, system 500, system 500 is initially configured with context item 530. Here, when system 500 is connected to another system in a network similar to network 100, context management framework 520 can determine that the system is a master system, and that context item 530 is to be distributed to the other system. Then, context management framework 520 invokes peer-to-peer agent 510 to establish a peer-to-peer session with the other system, and determines if the other system has received the context item 530. If not, then in its designation as the master system, context management framework 520 directs peer-to-peer agent 510 to provide a copy of the context item to the other system, and a context management framework in the other system installs the copy of the context item in the other system. In this way, system 500 operates to propagate the original context to other systems in the network.

FIG. 6 illustrates a method of peer-to-peer management through policy and context replication beginning at block 602. A context item, such as a new or updated policy, new or updated software or driver, a new or updated security key, or the like is received at a system in block 604. A decision is made as to whether or not the system that received the context item is in a network in decision block 606. If not, the “NO” branch of decision block 606 is taken, and the method ends in block 618. If the system is in a network, the “YES” branch of decision block 606 is taken, and a decision is made as to whether or not the system is a context management master system in decision block 608. If so, the “YES” branch of decision block 608 is taken and the method proceeds to block 614, as described below.

If the system is not the context management master system, the “NO” branch of decision block 608 is taken, the system negotiates to become the context the management master system in block 610, and a decision is made as to whether or not the system successfully negotiated to become the context management master system in decision block 612. If not, the “NO” branch of decision block 612 is taken, and the method ends in block 618. If the system successfully negotiated to become the context management master, the “YES” branch of decision block 612 is taken, and the method continues in block 614, as described below. If either the system is determined to be the context management master system, as determined in decision block 608, or the system successfully negotiated to become the context management master system as determined in decision block 612, the system establishes a peer-to-peer session with the systems in the network in block 614. Once the peer-to-peer sessions are established, the system sends the context item to the systems in the network in block 616, and the method ends in block 618.
